For everyone seeking clarification, let me see if I can explain the challenge chain more clearly.
Everyone who opts in gets put on a numbered list:
1. YLFer1
2. YLFer2
3. YLFer3
and so on. Once we know who's participating, I go to a random number generator and enter the number of people on the list. So if we have 20 people, I ask the generator to randomly select a number between 1 and 20.
Say it gives me the number 7. I see who is number 7 on the list, and I give that person a challenge. Maybe I know the person and what they're currently working on in their wardrobe, or maybe I have to go back and read some of their posts to learn more.
YLFer7 completes the challenge and posts photos. Applause ensues.
I then go to the random number generator and kick out a new number for YLFer7, who issues a challenge to that person. And so on. The last person on the list comes back around and offers a challenge to me, the challenge organizer who kicked off the whole chain.
Does that help explain things? (How I miss Hanna -- the originator of the challenge chains!)
